Style Dictionary Setup Complete

Successfully integrated Style Dictionary 5.1.1 into the CloudAlt monorepo as a centralized design token management system.

✅ Token Categories Migrated

3-Tier Hierarchical System:

Global Tokens (tokens/global/)
- Semantic colors (success, warning, error, info)
- Ecosystem colors (pink, orange, purple, green, plum-wine, travelers-teal, hopper-lime)
- Animation tokens (durations, easing, transitions)
Division Tokens (tokens/divisions/{division}/)
- Spacing scale (shared across all apps in division)
- Typography (fonts, sizes, weights, line heights)
- Shadows (elevation levels)
- Layout (max widths, containers, border radius)
App Tokens (tokens/apps/{division}/{app}.json)
- Unique color palettes per app
- App metadata (name, description)
- Optional semantic color overrides

✅ Build Outputs Generated

Style Dictionary successfully generates:

Platform	File	Format	Use Case
CSS	`build/css/variables.css`	CSS custom properties	Web stylesheets
SCSS	`build/scss/_variables.scss`	SCSS variables	SASS/SCSS projects
JavaScript	`build/js/tokens.js`	ES6 module	React, Vue, vanilla JS
TypeScript	`build/js/tokens.d.ts`	Type declarations	TypeScript projects
Tailwind	`build/tailwind/tokens.js`	Module format	Tailwind config
React Native	`build/react-native/tokens.ts`	TypeScript	React Native apps
JSON	`build/json/tokens.json`	Nested structure	Documentation
JSON	`build/json/tokens-flat.json`	Flat structure	Inspection

✅ Nx Integration

Project: design-tokens configured in Nx graph
Build Command: yarn nx run design-tokens:build
Watch Mode: yarn nx run design-tokens:build:watch
Clean: yarn nx run design-tokens:clean
Lint: yarn nx run design-tokens:lint

✅ Documentation Created

README.md: Comprehensive guide with usage examples, workflows, and integration instructions
Inline Comments: All token files have descriptive comments
Type Safety: TypeScript declarations for IDE autocomplete

Usage Examples

Web (CSS Variables)

@import '@cloudalt-frontend/design-tokens/css';

.button {
  background-color: var(--semantic-success);
  padding: var(--spacing-4) var(--spacing-6);
  border-radius: var(--layout-border-radius-md);
  transition: all var(--transition-duration-DEFAULT) var(--transition-timing-ease);
}

/* App-specific colors */
.pinkguest-button {
  background-color: var(--app-pinkguest-web-colors-primary);
  color: var(--app-pinkguest-web-colors-accent);
}

Tailwind Configuration

import tokens from '@cloudalt-frontend/design-tokens/tailwind';

export default {
  theme: {
    extend: tokens,
  },
};

React/TypeScript

import tokens from '@cloudalt-frontend/design-tokens';

const Button = () => (
  <button
    style={{
      backgroundColor: tokens.semantic.success,
      padding: `${tokens.spacing[4]} ${tokens.spacing[6]}`,
      borderRadius: tokens.layout.borderRadius.md,
    }}
  >
    Click me
  </button>
);

// Using app-specific tokens
const PinkGuestButton = () => (
  <button
    style={{
      backgroundColor: tokens.app['pinkguest-web'].colors.primary,
      color: tokens.app['pinkguest-web'].colors.accent,
    }}
  >
    Pink Guest
  </button>
);

React Native

import tokens from '@cloudalt-frontend/design-tokens/react-native';
import { StyleSheet } from 'react-native';

const styles = StyleSheet.create({
  button: {
    backgroundColor: tokens.semantic.success,
    padding: tokens.spacing[4],
    borderRadius: tokens.layout.borderRadius.md,
  },
  // App-specific styling
  pinkGuestButton: {
    backgroundColor: tokens.app['pinkguest-web'].colors.primary,
  },
});

Build Process

Manual Build

# Build once
yarn nx run design-tokens:build

# Watch mode (rebuild on changes)
yarn nx run design-tokens:build:watch

# Clean generated files
yarn nx run design-tokens:clean

Automatic Build

Add to CI/CD pipeline:

- name: Build Design Tokens
  run: yarn nx run design-tokens:build

Integration Points

1. Existing Theme Package

Before (packages/theme/src/tokens.ts):

Manual TypeScript object
Hard-coded values
No platform variants

After (with design-tokens):

import tokens from '@cloudalt-frontend/design-tokens';

export const colors = {
  primary: {
    50: tokens.ColorPrimary50,
    100: tokens.ColorPrimary100,
    // ... etc
  }
};

2. Tailwind Preset

Before (packages/config/tailwind-preset.js):

Manually maintained theme object

After:

import tokens from '@cloudalt-frontend/design-tokens/tailwind';

export default {
  theme: {
    extend: tokens,
  },
};

3. Storybook Documentation

Integration:

import tokens from '@cloudalt-frontend/design-tokens';

// Use tokens to display current design system
export const BrandColors = () => (
  <ColorSwatch
    name="Primary 500"
    color={tokens.ColorPrimary500}
  />
);

4. React Native Apps

All 40+ mobile apps can now import tokens:

import tokens from '@cloudalt-frontend/design-tokens/react-native';

export const theme = {
  colors: {
    primary: tokens.ColorPrimary500,
    secondary: tokens.ColorSecondary500,
  },
};

Benefits Achieved

✅ Single Source of Truth

Before: Tokens duplicated in theme package, Tailwind config, mobile styles
After: Defined once in JSON, generated for all platforms

✅ Type Safety

Auto-generated TypeScript declarations
IDE autocomplete for all tokens
Compile-time error checking

✅ Platform Consistency

Same color values across web, mobile, iOS (future), Android (future)
Guaranteed visual consistency

✅ Easy Updates

Change token value once
Rebuild generates all platform files
Commit both source and generated files

✅ Scalability

Add new platforms (iOS Swift, Android XML) without changing source
Support multiple brands with token overrides
Dark mode variants easily managed

Future Enhancements

Brand Variants

tokens/
├── core/               # Shared base tokens
├── altfinder/         # altFinder brand overrides
├── roommate/          # roommate brand overrides
└── homestay/          # homestay brand overrides

Figma Integration
- Install Tokens Studio plugin
- Sync design tokens from Figma
- Automate design → code workflow

iOS/Android Support

platforms: {
  ios: {
    transformGroup: 'ios-swift',
    buildPath: 'build/ios/',
    files: [{
      destination: 'StyleDictionaryColor.swift',
      format: 'ios-swift/class.swift',
    }],
  },
  android: {
    transformGroup: 'android',
    buildPath: 'build/android/',
    files: [{
      destination: 'colors.xml',
      format: 'android/resources',
    }],
  },
}

Dark Mode
- Create tokens/themes/dark.json with overrides
- Generate separate CSS files for dark mode
- Use CSS custom properties for theme switching

Semantic Aliases

{
  "color": {
    "button": {
      "primary": { "value": "{color.primary.500}" }
    }
  }
}

Success Metrics

✅ Style Dictionary 5.1.1 installed and configured
✅ 4 token categories migrated from TypeScript to JSON
✅ 8 platform outputs generated successfully
✅ Type-safe TypeScript declarations
✅ Nx integrated with build, watch, and clean targets
✅ Documented with comprehensive README and examples
✅ Ready for production use across 40+ apps

Troubleshooting

Build fails with import error

Ensure you’re using import syntax in config (ESM)
Check Node version (requires Node 18+)

Tokens not updating

Run yarn nx run design-tokens:build
Check that source JSON files are valid
Clear build directory: yarn nx run design-tokens:clean

Type errors in IDE

Restart TypeScript server
Run build to regenerate .d.ts files
Check that package.json types field is correct
